Dynamic Management and Netting of Transactions Using Executable Rules

ABSTRACT

Systems and methods for dynamically managing and netting transactions based on one or more sets of netting rules are disclosed. The present invention dynamically associates transactions with one or more collections based on the execution of netting rules to identify transactions that may be ideal for netting and to perform netting operations and calculations accordingly. The present invention may execute the netting rules according to the priority of the netting rule within a rule hierarchy and utilizes unique solutions allowing for the efficient processing of transactions even as netting rules are created, modified and removed from time-to-time. In addition, embodiments of the disclosed netting system utilize denormalized sets of data and maintain a complete audit trail for all operations.

FIELD OF THE INVENTION

Embodiments of the present invention are related generally to systemsand computer-implemented methods for the dynamic management and nettingof transactions according to a hierarchy of executable rules.

BACKGROUND OF THE INVENTION

In the financial services industry, investment banks and financialinstitutions enter into large numbers of transactions every month thatoften total in the trillions of dollars. Each of these transactions,which may be completed through money markets, foreign exchanges andderivative markets, to name a few, carries inherent credit, settlementand other financial and transactional risks when settled amongst tradingpartners. This is an especially large concern for investment banks andfinancial institutions that enter into thousands of transactions eachmonth. In response, various accounting solutions are utilized in theindustry to reduce these financial risks.

One such solution, “netting,” aggregates the transactional settlementvalue (e.g., cashflows) from multiple transactions, such as outgoing andincoming cashflows from market trades, in order to create a singlesettlement type payment on a given payscale. Netting may take severalforms. Netting by novation, for instance, is where existing obligationsare discharged by replacing them with a new obligation. When two tradingpartners agree to obligation netting, they are legally bound to netamounts from two or more trades due in the same currency for settlementon the same day. Counterparties in foreign exchange transactions, forexample, may be required to settle all of the trades included under theagreement by either making or receiving a single payment, therebyreducing the risk by lowering the number and size of payments that wouldotherwise be needed to settle the underlying transactions. Another typeof netting, close-out netting, is an arrangement to settle allcontracted, but not currently due, liabilities to and claims on aninstitution by one single payment immediately upon the occurrence of oneof a list of defined events.

Because many of these transactions often involve the same parties, thefinancial obligations between these common entities may be aggregated todetermine a reduced net obligation. By reducing the total number ofsettlements between the parties, the operational and settlement risksand costs, the cashflows visible in the market, and the credit exposureto the financial institution, may all be reduced.

Despite being a common accounting technique, the implementation of“netting” in the financial services industry has been rudimentary atbest. Indeed, the process of netting is typically initiated manually andwith elementary computer systems and solutions. For example, manyentities implement the netting technique by utilizing one large databasethat stores all transactional and settlement obligations. A trader ormanager may manually traverse and select the particular transactionsfrom the database to group together the transactions for netting. This,as a person of ordinary skill in the art may recognize, can be timeconsuming and ultimately inefficient as it may often be difficult todetermine which transactions to select among tens of thousands oftransactions across multiple markets and currencies involving thousandsof different entities, subsidiaries and related corporations.Furthermore, the transactions that are netted and the settlements ofsuch transactions are manually recorded. This is especially burdensomeand problematic when the settlement values change from day to day, evenafter settlement.

Furthermore, the current implementations often require the directmanipulation of the cashflow and/or transaction data within thedatabase, effecting the entities' obligations to track its records foraudit and disclosure purposes. As a result, transactional and nettingrecords, if they are kept in the first place at all, are often lost overtime as the data is modified in response to changing market conditionsand transactions.

While the use of a computer database allows a person to access the dataof the transaction, it may, nonetheless, be difficult to find theparticular transaction that would benefit the company and reducefinancial risks through netting. This is especially difficult in theface of tens of thousands of transactions, each containing variables andsettlement requirements that change often.

With the fast-changing nature of day-to-day trades and othertransactions, there is, accordingly, a need to dynamically determine thetransactions that should be netted and to determine the net-position ofany number of transactions (i.e., how much is owed, or is to be paid,when it is time to settle), even when settlement values change.Furthermore, there is a need to dynamically keep a recorded trail ofnetting related actions.

SUMMARY OF THE INVENTION

The presently disclosed invention satisfies the above-described needsfor an improved system and method for the dynamic management andprocessing of transactions for netting purposes. Specifically, theinvention provides a system and method for dynamically determining,grouping and processing transactions according to netting accountingpractices based on a hierarchy of rules that are executable by aprocessing unit. In the present invention, there may be any number ofhierarchal rule levels and, in one preferred embodiment,transaction-specific rules that are executed first and general rulesthat are subsequently executed if the specific rules do not apply to aparticular transaction or cashflow. The netting rules that are created,amended, and/or deleted, may dictate the association of transactionswith one or more collections and the determination of the net settlementvalues.

In one aspect of the present invention, a computer system to dynamicallymanage transactions for netting one or more transactions associated witha collection is disclosed. The computer system includes a database forstoring data of the transactions and a netting engine for performingvarious operations related to the netting of the transactions. Forinstance, in one embodiment of the present invention, the netting enginemay associate one or more transactions with a collection based on ageneral rule set and a specific rule set. The netting engine may furtherdetermine a net transaction value based on the transactions that areassociated with the collection and cause the transaction to settle basedon the determined net transaction value.

In one embodiment of the present invention, the netting engine mayassociate the one or more transactions with a collection based on a rulein the specific rule set. The netting engine may also associate thetransactions with a collection based on a rule in the general rule set,where the transactions are not associated with at least one collectionbased on a rule in the specific rule set. In one preferred embodiment,the netting data contained in the database may include a rule identifierfor each of the transactions, identifying the rule associated with thetransaction, if any.

In yet another embodiment of the present invention, the netting enginemay automatically associate a transaction with and/or disassociate atransaction from a collection when the transaction is added, amended orremoved. Further, in another embodiment, the netting data in thedatabase may be automatically updated in response to the associating,determining and causing operations of the netting engine. In yet oneother embodiment, the present invention will further include a ruleengine for managing the rules. The rule engine, in one instance, mayhave the capability to automatically generate one or more rules in thegeneral rule set or the specific rule set.

In another aspect of the present invention, a netting system isdisclosed for netting one or more transactions that are associated witha collection in accordance with a netting rule. The computer system mayinclude a denormalized transaction database, which includes data foreach of the one or more transactions, such as a rule identifier. Thedisclosed netting system may also include a netting engine to performvarious operations using a processor. For example, it may be capable ofassociating the one or more transactions with the collection inaccordance with a general rule set and a specific rule set, determininga net transaction value for the collection, and causing a settlement ofthe one or more transactions associated with the collection based on thedetermined net transaction value.

In one embodiment, the netting engine may associate one or moretransactions with a netting rule in response to the updating of the ruleidentifier to identify the netting rule associated with a transaction.This may cause the transaction to be associated with a collection thatmay be associated with the netting rule. In response to the updating ofthe rule identifier with a value of null, the netting engine maydisassociate the one or more transactions with a netting rule. This mayalso cause the transaction to be associated with a different collection,such as a general collection. In yet another embodiment, the nettingengine will associate the one or more transactions with a collection ifthe one or more transactions are not associated with at least onecollection based on a rule in the general rule set.

In yet another aspect of the present invention, a method of netting oneor more transactions according to a netting rule is disclosed, which mayinclude the steps of associating the one or more transactions with acollection in accordance with a general rule set and a specific ruleset, determining a net transaction value for the collection, and causinga settlement of the one or more transactions associated with the nettinggroup based on the determined net transaction value.

In one other aspect of the present invention, a computer system todynamically manage transactions for netting one or more transactionsassociated with a collection is disclosed to include a database, anetting engine and a rule engine. The database may be stored in memoryand may include netting data of one or more transactions. This nettingdata may include a rule identifier for each of the one or moretransactions. Furthermore, the netting engine may utilize processorcomponents to perform various operations including automaticallyassociating one or more transactions with a general collection inaccordance with a rule in a general rule set in response to the addingof the one or more transactions and automatically updating the nettingdata in response. In addition, the netting engine may automaticallyassociate the one or more transactions with a specific collection inaccordance with a rule in a specific rule set in response to themodifying of the rule identifier to identify the rule associated withthe transaction. It may further determine a net transaction value forthe netting group associated with the one or more transactions and causea settlement of the one or more transactions associated with the nettinggroup based on the determined net transaction value. Furthermore, theengine may automatically update the netting data associated with thetransactions in response to the settlement. In addition, the rule enginemay automatically generate rules, each of which may define attributes ofthe one or more transactions based on the transaction's currency,trading partner, amount of the transaction, and/or date of thetransaction.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the presently disclosed invention are directed to asystem and method for the management and netting of financialtransactions.

FIG. 1A is a block diagram illustrating a netting system 100 inaccordance with an embodiment of the present invention, comprising anetting engine 104, a rule engine 108 and a netting database 112. Abroad overview of the invention will be discussed, followed by a moredetailed discussion of the capabilities and features of the nettingdatabase 112, the rule engine 108 and the netting engine 104.

The netting system 100 facilitates the netting of transactions bydynamically managing the transactions of the entity, identifying thetransactions that may be ideal for netting, determining their netsettlement value, and causing the settlement of the transactions. Thenetting system 100 performs these tasks in accordance with one or moresets of netting rules that may be configured to be hierarchal in nature.The netting system 100 dynamically performs these tasks even astransactions are completed, modified and removed from the system.Similarly, the present invention contains unique features that allowtransactions to be efficiently and dynamically assigned to one or morecollections even as nettings rules are created, modified or deactivated.

The presently disclosed invention may be used by an investment bank thatparticipates in trading in a number of financial markets and which seeksto reduce the risks in settling transactions. While the exemplarysystems and methods described are shown to manage the netting of tradesand derivatives in the financial industry, the present invention may beput into practice in any industry to manage financial transactions andthe settlements between trading partners. For example, the nettingsystem 100 may also be configured for use by a manufacturing companythat purchases resources and sells products.

The netting system 100 receives transactions as they are completed andstore the transaction information within the netting database 112, alongwith various other data. In operation, the netting system 100 maygenerate and utilize denormalized sets of data at the netting database112 containing information about each transaction, along with referenceand other information that is utilized in the operation of the nettingsystem 100. Such information may include each transaction's associationswith other transactions, collections, netting rules and settlements.Other embodiments may store and utilize the original transaction data asit is received at the netting system 100. The netting database 112 mayalso store all versions of transactions, collections, rules andsettlements as they are created, modified, and removed.

The netting system 100 may not process transactions received for netting(e.g., associate a transaction with a collection for netting), untilsuch transactions are made available for netting. In certainembodiments, the generation of a denormalized transaction data page atthe netting database 112 automatically causes the netting system 100 toprocess the transaction for netting. In several other embodiments, thisoccurs when a flag or other indicator within a transaction data page istriggered (e.g., when a data value is set to “true”).

Once a transaction is available to be processed by the netting system100, the netting system 100 may associate the transaction to one or morecollections according to configurable netting rules that define thespecific transaction or the type of transaction that should beassociated with a particular collection. Thus, a collection may identifyto a user a set of transactions having similar attributes, which theuser may then use to select one, some or all transactions within thecollection from which to perform netting. A collection may also identifyspecific transactions, as specifically chosen by a user for netting.This may, in several embodiments, cause the automatic generation of oneor more netting rules which then results in the association of thetransactions with a collection.

The netting system 100 may be configured to execute netting rules inorder of priority according to a configurable rules hierarchy. Certaintypes of rules may have priority over others, wherein higher priorityrules will control a transaction's association over lower priorityrules. In the preferred embodiment, there are two levels of rules:general rules and transaction-specific rules. When a transaction isreceived, the netting engine 104 may associate the transaction with acollection by executing or processing one or more of such netting rulesconfigured at the netting system 100.

The association of transactions to a particular collection may also beperformed at the creation, modification or removal of one or morenetting rules by a user. For example, the rule engine 108 mayautomatically generate a rule and the netting engine 104 mayautomatically associate the transactions with a collection in responseto a user selecting transactions for netting. Associations withcollections may also be determined by the netting engine 104 in responseto the modifications or removal of transactions previously received atthe netting system 100.

Once transactions have been associated with a collection, the nettingengine 104 may automatically determine the net transaction value for thecollection according to netting accounting practices that are utilizedand well known in the art by a person of ordinary skill. The nettingengine 104 processes the settlement value of each of the transactions ina collection, such as by aggregation. Other manners of calculating thenet settlement value may be used. The calculation of the net settlementvalue may be automatic when a collection is created or modified, atregular intervals, or upon the command of the user.

In practice, once the net settlement values of a set of transactions areknown, the netting engine may provide a user of the system with theinformation for approval of the settlement via a user interface. In onesimple embodiment, the user of the system may communicate thetransactions and settlement information with the trading partner throughtraditional methods such as by telephone or email. This negotiation andapproval process may alter the transactions that are to be settled andthe settlement values. Once the trading partner has approved thesettlement, the user of the system may indicate to the netting systemthat the settlement has been approved. In several embodiments, discussedin detail in other portions of this disclosure, the approval andnegotiation process may be built into the system, allowing thenegotiation and approval of settlements to be performed seamlesslybetween the netting system 100 and the trading partner and itssystem(s).

Once a collection of transactions has been approved for settlement, thenetting engine 104 may cause the transactions associated with thecollection to be settled according to the agreed upon net settlementvalue. For example, the netting engine 104 may cause an engine withsettlement capabilities to settle the particular transactions accordingto the determinations of the netting engine 104. The netting engine 104may communicate to this settlement engine the specific transactions thatshould be settled and the parties involved, for example. In anotherembodiment, the netting engine may have such settlement capabilitiesbuilt in.

In either case, the net settlement value may be delivered to the tradingpartner and the trading partner may be notified of the settlement.Information as to how the net settlement value was calculated may beprovided to the trading partner as well. In one embodiment, thesettlement may be scheduled according to a determined payment schedule.Once the settlement has been completed, the netting engine 104 willupdate the netting database 112 with the settlement information, whichmay include the settlement value, the time of settlement, and thetrading partners involved. The netting engine 104 may also associate thesettlement information with the collection information within thenetting database 112 such as by including reference information.Furthermore, the netting engine 104 may record the settlementinformation with each of the transactions associated with the collectionsettled. At the same time, the transactions data in the netting database112 may each, individually, be marked as settled.

As depicted in FIG. 1B, the netting system 100 may be connected to aclient device 114 over a local network 122, which may be used by a userto view the pending transactions at the netting system 100, to selecttransactions for nettings, to determine net settlement value, to settletransactions, and to create rules, to name a few capabilities.

Furthermore, the netting system 100 may be connected, via the localnetwork 122, to a central transaction system 116, which facilitates anentity's day-to-day transactional operations. For example, the centraltransactions system 116 may allow a company to complete trades in anumber of financial markets. Similarly, the central transaction system116 may facilitate the completion of transactions with other companiesand entities. The operations of the central transaction system 116 maybe controlled by a central transaction engine 118 and the data oftransactions utilized by the engine 118 may be recorded at a centraltransaction database 120. In operation, transactions that are completedand entered into at the central transaction system 116 may automaticallybe received and processed at the netting system 100 in response.

In another embodiment of the present invention, the netting system 100may simply be incorporated into the central transaction system 116.Thus, it would be readily apparent to one of ordinary skill in the artthat the present invention can be adapted to operate with existingsystems of corporations and entities with minimal cost. In effect, anycompany with an existing transaction infrastructure may greatly expandthe capabilities of its transaction system(s) to include the ability toautomatically perform netting operations without having the need toexport sensitive company transaction data to an external system, whichtend to come with increased security risks, financial risks, andoperational costs. It would be apparent to one of ordinary skill in theart that the central transaction system 116 may contain additionalengines, databases, and components or may contain only one or more ofthe engines and/or databases depicted. Further, central transactionsystem 116 may contain communication channels not shown, such ascommunication channels with other internal and external systems wellknown in the art.

The netting system 100 may further be connected to a network 124, whichallows it to connect to a plurality of devices and systems includingtrading partner system 126, client device 128, financial market 130,bank 132, trading partner 134, and regulatory agency 136. A user of thenetting system 100 may access the system from client device 128 tocreate a netting rule and to perform netting operations, for example.Furthermore, the netting system 100 may communicate with trading partnersystem 126, financial market 130, bank 132, and trading partner 134 tocomplete settlements with trading partners and to deliver nettinginformation as needed. Similarly, the netting system 100 may communicatewith regulatory agency 136, such as the Securities and ExchangeCommission, the Financial Industry Regulatory Authority (FINRA), stateand local regulators, and other regulatory agencies. The netting system100 may transmit and disclose the transactions that have been settledincluding the settlement value. Such disclosure may be in a form thatmay be processed by a computer system of the regulatory agency 136,including by use of an application programming interface (API) or be assimple as disclosure documents well known in the art. Through the use ofnetwork 124, the netting system 100 may also allow the regulatory agencyto have access to the netting system 100 including a portion (e.g.,public portion) of the netting database 112, thereby allowing the agencyto track transactions that may be settled and to analyze the dataaccordingly. The netting system 100 may also be configured to allowaccess by agents of the regulatory agency 136, at predetermined periodsaccording to regulations, to examine the financial transactions andsettlements. The regulatory agency 136 may, therefore, have access toall transactions, collections, rules and settlements including versionsof each over time. The netting system 100 may be configured toautomatically transmit transaction, netting/settlement records to theregulatory agency 136 at regular or required time intervals inaccordance with financial regulations of the regulatory agency 136. Thenetting system 100 may also be configured to automatically generate thefinancial disclosures, inputting various financial data (aggregated orotherwise) into disclosure forms and formatting the disclosure data asrequired. Such actions may be configured to take place at regularpredetermined times or upon command.

The netting engine 104may operate by communicating with rule engine 108 and transactiondatabase 112 by utilizing a network such as local network 122 or tonetwork 124.

Having described the general operations at the netting system 100, thenetting rules, as utilized by the system 100, will now be discussed,followed by a detailed description of the operations and capabilities ofthe engines and databases making up the netting system 100.

Netting Rules

Netting rules are configurable policies that associate one or moretransactions with a particular collection when processed or executed atthe netting system 100. Therefore, netting rules may be used to groupsimilar types of transactions together for a better understanding of thetransactions that are eligible for netting. Even further, netting rulesmay be used to associate particular transactions to a collection forprocessing according to netting accounting practices and for determininga net settlement value.

A netting rule is said to “capture” a transaction if the transaction hasall of the attributes that are required by a netting rule. For example,a netting rule may be defined to capture all transactions from aparticular trading partner having a settlement value over $1000. A userof the system, for instance, may define the transactional attributes andthe conditions for association to a collection, based, at least in part,on these attributes. When a netting rule is executed (i.e., processed bythe netting system 100), all transactions meeting the requirementsdefined by the netting rule will be associated with a collection.

A netting rule may also define what actions should be taken when atransaction having such attributes are found within the system,including which collection(s) to associate with a transaction, when toassociate the transaction to a collection, when to perform netting, andwhether to complete the settlement of the transaction automatically, toname a few.

A configurable hierarchy of netting rules determines which netting rulesmay control when more than one such rule captures a particulartransaction. In the preferred embodiments of the present invention,there are two types—or levels—of netting rules: general rules andtransaction-specific rules. General rules may be utilized to organizethe transactions into one or more collections according to one or moredefinable attributes of the transactions. General rules may also be usedto allow a user to understand the various transactions that may requiresettlement. For example, a user may organize the transactions forviewing or for netting according to the value of the transaction,placing transactions with a value of less than $100 in one collection,transactions with a value from $100 to $1000 in a separate collection,and transactions with a value greater than $1000 in yet anothercollection. A transaction may also be associated with a collection ifthe transaction is a trade through a particular financial market, suchas the NASDAQ stock exchange. In another embodiment, it may also bepreferable to associate all transactions involving a particular entitywith a collection. This is especially useful where that entity isinvolved in a large number of transactions. In yet another embodiment,it may be preferable to group all transactions that are completed usinga particular currency, such as the Dollar. A person of ordinary skill inthe art would recognize that with this feature, any number and varietyof attributes may be used to monitor transactions having particularattributes ideal for netting. A general rule may also be used toorganize transactions into one or more groups for netting based on suchattributes. A user, therefore, may not only organize types oftransactions into discernable groups, but the user may also select anyof these collections for netting.

Transaction-specific rules, in contrast, identify specific transactionsthat have been selected by a user or administrator for netting. As such,a user may utilize a user interface to select a transaction or enter atransaction identifier to generate a transaction-specific rule. Theresult is a collection containing the selected transactions.

The transaction-specific rules may further be defined to assignparticular transactions that have been selected into one of severalcollections for netting based on the attributes of the transaction,similar to general rules. For example, of the transactions that areselected for netting, transactions with trading partner A mayautomatically be associated with a collection while transactions withtrading partner B may be associated with another collection, forexample.

Notably, in a preferred embodiment, transaction-specific rules areexclusive in scope. In other words, a transaction (including subsequentversions) may be captured by only one transaction-specific rule. Thisallows for efficient processing of transactions and their associationsto collections when rules are created, modified or deleted.

The transaction-specific rules, also, have priority over the generalrules. That is, it may first be determined whether a transaction isassociated with a collection according to the transaction-specificrules. Only when a transaction is not associated with a collectionaccording to these rules, are the general rules examined.

It should be readily apparent to a person of ordinary skill in the artthat any number of types of rules with any hierarchy of netting rulesmay be used and are well within the scope of the presently disclosedinvention. Furthermore, it is further well within the scope of thepresent invention to implement the present invention to utilize nettingrules that are not exclusive in nature. For example, rather than havingnetting rules that are exclusive in nature, each level of rules in ahierarchy of rules may be prioritized such that when a transaction maybe captured by two or more rules, the priority information mayautomatically determine which rule should be applied. As anotherexample, where there are two or more rules that capture a particulartransaction, both rules may be applied to the transaction. In suchcases, a transaction may be associated with a number of collectionsbased on these rules.

Netting Database

The netting database 112 is utilized by netting engine 104 in managingtransactions of the system, associating the transactions withcollections for netting, and tracking netting, transaction andsettlement data over time. FIG. 2A depicts a block diagram of a nettingdatabase 200 in accordance with at least one embodiment of the presentinvention, containing transaction data 204, collection data 208,settlement data 212, and rules data 216.

The transaction data 204 of the netting database 200 contains aplurality of data pages, each corresponding to a transaction that isreceived at the netting system. Each transaction that is received at thenetting system 100 may contain a settlement amount, which is an amountthat is owed to a trading partner, or conversely, an amount that thetrading partner may owe. This value may be identified and will bereferred to herein as a settlement value (i.e., the amount that is to betransferred upon settlement). In one embodiment, the settlement amountin each transaction page is a positive amount indicating the absolutevalue for settlement. In addition, each transaction page may containinformation indicating whether the amount is to be paid or to bereceived. In another embodiment, a positive settlement data value in atransaction page indicates the settlement amount to be paid to thetrading party while a negative settlement data value may indicate anamount that is owed by that party.

An exemplary transaction page is depicted in FIG. 2B. As seen, eachtransaction page may include: a unique transaction identifier, theparties involved (e.g., trading partner, company X), the transactionsettlement value, the trade quantity and price (e.g., 100 shares for500), the currency (e.g., the Euro), the trading market if applicable(e.g., derivatives market), corresponding transaction contract, if any,the settlement schedule (e.g., to settle within 30 days of trade), andany other stipulations or notes that may have been agreed upon by theparties. Other information may be included depending on the transactiontype, the commodities involved, and the financial market utilized, aswould be understood by a person of ordinary skill in the art. Atransaction page may contain additional information that facilitates theoperations of the netting system including time and date of when thetrade was entered and received, the date and time the transaction datapage was generated and the version of the transaction page, thesettlement status, the settlement history, the date that it was lastmodified etc., (also depicted in FIG. 2B).

Each transaction page may further contain reference data, allowing thenetting engine 104 and rule engine 108 to determine the transactionpage's relationship with other transactions. For example, in the tradesof derivatives, multiple transactions (i.e., cashflows), may be agreedupon by the parties at one time. Each transaction data page for suchtransactions, therefore, may reference other transaction pages, allowinga user of the system to quickly determine related cashflows, such asthose making up a single trade of derivatives. For example, thetransaction shown in FIG. 2B is related to three other transactionswhich are identified within the transaction page by their transactionidentifiers (i.e., T12245125611, T12245125613, and T12245125614). Notethat transactions, as with collections, settlements and rules, may bereferenced by an identification number that makes no reference to itsversion. In operation, the engines of the netting engine 104 may havethe capability to determine, based on the transaction identifier, themost up-to-date version of the transaction, collection, settlement, orrule that is referenced.

In some embodiments, each transaction data page may also containreference information of the collection that a transaction page isassociated with and the settlement pages related to such collections,allowing a user to determine which collection a transaction isassociated with and any settlements that may have taken place.

Each transaction page may further contain reference data of atransaction's association with one or more netting rules. In a preferredembodiment, the transaction pages may identify a transaction'sassociated general or transaction-specific rule. The netting engine 104may utilize such data in determining the association of transaction to aparticular collection. By storing and tracking the transaction-specificrule from which a transaction is captured, the netting engine 104 mayefficiently process a transaction when a transaction-specific rule iscreated, modified or deleted. Indeed, as discussed with respect to thenetting engine 104 and in other portions of this detailed description,the use of such reference data allows the netting engine 104 to avoidthe reexecution all transaction-specific rules and save processingresources. For example, if a transaction-specific rule is removed, thetransactions that are captured by the transaction-specific rule prior toits modification may be determined and their disassociation from acorresponding collection may be processed efficiently. In such cases,rather than having to reexecute all transaction-specific rules—which maynumber in the tens of thousands—only the general rules may bereexecuted. This is discussed in further detail with regard to theoperations of the netting engine 104.

The transaction data 204 contains a transaction page for each version ofa transaction. When information contained within a transaction page ismodified, a new transaction page may be generated to reflect thetransaction information as modified. In addition, subsequent versions ofa transaction page may reference the previous versions in order topreserve an audit trail of the transactions, netting and settlements atthe netting system, as seen in FIG. 2B. The transaction ID may be usedto reflect different versions of a transaction. For example, thetransaction page of FIG. 2B is version 2 of transaction T12245125612.Therefore, it has been assigned the ID number, T12245125612.2. Othermethods of preserving an audit trail may be also be utilized.

The transaction data 204 corresponds to transactions that have beenreceived at the netting system 100. According to the preferredembodiments of the present invention, a transaction may be associatedwith a collection and settled with other transactions only when thetransaction is first made available for netting. The netting system maybe configured to monitor the transaction data for an indicator that,when satisfied, may allow the netting system 100 to process thetransaction in the manners discussed in this disclosure.

In one preferred embodiment, a transaction is available for netting whena denormalized transaction page is created in the netting database 112.This denormalized transaction page may be a copy of the transaction thatis received at the netting system 100 and contain information related tothe transaction itself, such as the transaction value, partner, price,currency, market and other information well known in the art. Thedenormalized transaction page may further contain additional informationthat is utilized in the operation of the netting system 100, such as thereference information and metadata information discussed above. Asdiscussed in detail with the discussions of the netting engine 104, thecreation of a denormalized transaction page may indicate to the nettingengine 104 that the transaction is available for associating with acollection/rule and for settlement.

In other embodiments, the transaction that is received at the nettingsystem may be directly stored at the transaction data 204 as atransaction page. In addition, the transaction page may contain a flagor other forms of indicators that, when triggered (i.e., an“available4Netting” variable equals “true”), allow the transaction pageto be processed for netting. The netting engine 104 may monitor thenetting database for changes of such variables.

The collection data 208, similar to transaction data 204, contains dataof collections in the form of collection pages, with each pagecorresponding to a collection. Each college page may include thecollection identifier, the net settlement value, and the time that thenet settlement value was determined, as seen in FIG. 2C. Furthermore, itcontains reference data of each of the transactions associated with thecollection. In at least one embodiment, each collection page alsocontains reference data identifying one or more settlement transactionsin the settlement data 208 (e.g., a settlement page). Like thetransaction pages, the collection pages may further contain referencedata identifying previous and future versions of the collection page. Inat least one embodiment, a collection page further references a nettingrule that captured its associated transactions.

The settlement data 212 contains settlement records for each of thecollections that have been settled. For each settlement, a settlementpage in the settlement data 212 of the netting database 200 exists andmay include a settlement identifier, the amount settled, the partiesinvolved, the banks used, and transaction status (e.g., settlementverified, check sent, etc.). An exemplary settlement page is depicted inFIG. 2D. Each settlement page may further contain reference data to thecollection that the settlement is associated with and contain referencedata to past and future settlements.

The rules data 216 may contain data for each of the rules that have beencreated and used in the past. Each rule, which may be stored in therules data 216 as a rule page, such as the one depicted in FIG. 2E, mayinclude a unique rule identifier, the rule type, the rule's hierarchalpriority, and the netting rule itself (e.g., desired attributes of atransaction). In addition to the use of attribute variables andconditions, a rule may be defined according to the time that thetransaction was completed or last modified (e.g., at least 1 hour beforea cut-off time), or the status of the transaction (e.g., whether asettlement has been entered, whether it has been modified aftersettlement). More sophisticated rules may be created utilizing otherdatabases that may be available to the netting engine. For example, anetting rule may be defined based on the size of a trading partnercorporation, the interest rates set by financial regulators, profitmargin of a subsidiary of the trading partner, and the current daterelative to the fiscal quarter.

Each rule page may further define actions that the netting engine 104may take upon the execution of the rule. In addition to checking thevariables, conditions and other data in associating transactions with acollection, the rules may be configured to cause the netting engine 104to calculate the net settlement value automatically or to automaticallycause the settlement of the collection upon the completion of theassociation process, for example.

In at least one embodiment, various versions of rules, as they arerevised, are also maintained at the netting database 200. Thus, eachrule page may reference previous and future versions of rules. In someembodiments, rule pages may further contain reference information ofeach transaction or corresponding collections that it has captured whenexecuted.

In some embodiments of the present invention, the netting database 200may maintain the original data of transactions as they are completed.Indeed, the netting database 200, in some of these embodiments, may beutilized by other engines and systems external to the netting system,such as by the central transaction system.

The presently disclosed invention may be configured in a manner thatensures data integrity and allows for a complete audit trail.Transaction information may be stored in the form of denormalizedtransaction pages. In other words, the original transaction data, whichmay be stored at the netting system 100 or in other systems or databasesof the company (e.g., the central transaction database 120 of FIG. 1B)is not directly manipulated by the netting system 100. Furthermore, allmodifications and deletions to transaction, collection, rule, andsettlement data, results in the creation of a new corresponding datapage containing the data as modified or deleted. Thus, each version of atransaction, collection, rule and settlement may be stored at thenetting database. Furthermore, the association between each transaction,collection, rule and settlement is also stored, along with anymodifications of such relationships. Thus, a complete audit trail ismaintained at the netting system 100. This allows for users of thesystem as well as outsiders (e.g., regulatory agency 136 of FIG. 1B) totrack how an entity is performing its netting operations at any givenmoment. For example, based on a single settlement, a regulator may beable to determine all transactions associated with the settlement andrelated settlements, the various modifications made to each transactionfrom the creation of the transactions to the latest settlements, thevarious net settlement value calculated along the way, the person whoapproved the various settlements, the person who approved the initialtransactions, and so on. In other words, the transactions, collections,settlements and rules in existence at the netting database at any givenpoint in time may be traced forwards and backwards as necessary ordesired.

While the netting database 200 is depicted in FIG. 2A as a singledatabase, it may be implemented as one of a plurality of nettingdatabases, with each database containing data of differing sets oftransactions. In another embodiment, each database may contain aparticular type of data or category of information, such as data of aparticular type of transaction, data of collections, or data ofsettlements.

Rule Engine

The rule engine 108 manages the rules that are utilized by the nettingsystem 100. In one embodiment, the rule engine 108 allows for a user ofthe netting system 100 to create, modify and remove netting rulesthrough the use of a user interface. The user interface, for example,may allow the user to define the various attributes of transactions thatthe user would like to be associated with a collection, and in certaininstances, to perform netting. The rule engine 108 may alsoautomatically generate rules according to user actions. For example, inresponse to the selection of transactions for netting, the rule engine108 may automatically generate a transaction-specific rule as to capturethe transactions chosen.

In an embodiment, the user may further set, via the user interface, whennetting rules in the netting system 100 may be processed. The ruleengine 108, for instance, may be configured to execute each netting ruleas they are created or modified and to process various transactionsaccordingly when a rule is removed. The rule engine 108 may also beconfigured to execute newly created rules or reexecute modified rules atregular intervals, at a scheduled time, or at the instruction of a user.

In one embodiment of the present invention, the rule engine 108 furtherhas the capability to generate rules automatically without user request.It may generate rules to group transactions together according to thetransactions available for netting, according to the conditions of thesystem, and according to information from external sources. The ruleengine 108 may create not only general rules to present to the user thetransactions in a manner that will facilitate the identification oftransactions for netting, but the rule engine 108 may also proposetransaction-specific rules that select transactions that should beassociated for netting. It may automatically calculate the netsettlement value of the resulting collections accordingly.

The rule engine 108 may examine the various transactions at the nettingdatabase 112 for patterns and trends, taking into considerationattributes of transactions that may be ideal for netting or simply thosetransactions that should be distinguished from other transactions.Attributes such as prices, quantity and the market used, may give fairindication of when a set of transactions should be associated togetherand provided to the user for netting. For example, the rule engine 108may create a general rule to group all transactions with a particulartrading partner together when it determines that the number oftransactions with this trading partner is much greater than the averagenumber of transactions with other trading partners. Similarly, it maygroup all transactions that are completed in a certain currencytogether, recognizing that the use of a particular currency in atransaction is rare. Furthermore, it may take into consideration thesettlement dates of the transactions. Transactions that are nearing acontract settlement date may automatically be grouped with one anotherby the rule engine 108 for netting. In addition, conditions of thesystem may cause the generation of a netting rule. Transaction-specificrules may automatically be generated if the system is overloaded withunsettled transactions in order to facilitate the netting of thetransactions and to free up system resources.

The rule engine 108 may further take into consideration historical dataon settlements, netting and association when grouping one or moretransactions via a general rule, taking into consideration internal andexternal records and data. It may choose transactions for netting thathave similar attributes to those transactions that have been netted inthe past. Similarly, it may generate rules that will capture acollection of transactions of similar structure or attributes to othercollections of transactions that have been netted in the past. Furtherstill, it may generate rules with net settlement values nearing what hasbeen entered into in the past. Such determinations may also take intoconsideration previous records of user approvals of engine-generatedrules.

The rule engine 108 may also automatically create such rules atpreferable times and system conditions, according to common nettingpractices in the art. For instance, the rule engine 108 mayautomatically create a general rule at or near the daily cut-off timeand it may associate dynamically the most number of transactionspossible involving a common trading partner, currency and market thatwill result in a net settlement value of 0, or closest possible.

The rule engine 108 may provide the user with proposed netting rules forexecution, including the transactions that would be involved and the netsettlement value of the resulting collection should the rule beexecuted. In certain embodiments, the user may access, at any time, adynamically generated list of proposed collections that are generated bythe rule engine 108. The user may then select to view the potentialeffects of such transactions and may proceed to approve any one of theproposed collections. In these embodiments, the netting rules aretherefore not processed until a user has approved a propose rule. Thus,a proposed rule is just that, a rule that if executed, would result inthe association of the determined transactions into a collection andresult in a determined settlement value, if settled. In one embodiment,no transaction pages or collection pages are generated and stored at thenetting database 112 until the user approves the netting rule forexecution. In one embodiment, such proposed information is stored in thenetting database 112 in a proposed data portion of the netting database112. In another embodiment, such pages are generated and stored at thenetting database 112 but may marked as proposed transactions,collections and settlement values.

The Netting Engine

The netting engine 104 facilitates the netting of financial transactionsby organizing and identifying transactions for netting, determining thenet position for each of these collections and causing the settlement ofeach of the netted transactions based on the net positions determined.

The netting engine 104 may be configured to operate with any type oftransactions that require settlements between two or more tradingpartners. For example, a transaction may be a trade of financialsecurities, commodities and other tradable items and instruments ofvalue in a financial market such as a stock market (both primary andsecondary), bond market, commodity market, money market, foreignexchange market, insurance market or derivatives market. Transactions donot have to be completed through a financial market at all, but instead,may simply involve two or more parties directly exchanging commoditiesand instruments. Such transactions may be for a sale of a commodity(e.g., food, metals, electricity) in exchange for other goods or forcash. A transaction may also contain multiple unique obligations. In onepreferred embodiment, trades are received and are entered into thenetting system, with each trade containing numerous cashflowsrepresenting an individual obligation to the trading partner. In theseembodiments, each cashflow may represent a transaction.

These transactions may involve any number and type of entities. Thetransactions may involve two or more financial entities that initiateand complete trades in one or more of the financial markets describedabove. For instance, the parties may be two or more investment banks,each making various trades with the other and accumulating a number ofindividual obligations over a period of time. Other types of entitiesmay include individual companies, insurance companies, credit unions,financial advisers and brokers, pension funds, mutual funds, variouscollective investment schemes, and others. Indeed, a transaction may becompleted by any entity that may have settlement needs, including anycompany that has outstanding debt or obligation with the same partyacross multiple transactions.

In a financial market trade, the transaction may be received when astock purchase from a particular entity is complete. For example, atransaction may be completed through the use of the central transactionsystem 118 and provided to the netting system 100 for possible netting.The netting engine 104 may receive a transaction when it is completedor, in various embodiments, may retrieve transactions that have beencompleted at regular intervals, at a predetermined time or at a user'srequest. In yet another embodiment, the central transaction system 116may provide the netting system 100 with notifications at regularintervals of transactions that have recently been entered at the centraltransactions system 116. The netting system 100 may retrieve some or allof the transactions based on the user's request or predeterminedcriteria.

In response to receiving a new transaction, the netting engine 104 mayprocess the transaction by generating and storing a transaction page inthe netting database 112. In one preferred embodiment, the nettingengine 104 may generate a denormalized transaction page containing atleast some of the transaction information received at the nettingengine. In fact, in the preferred embodiment, it would contain all ofthe same data contained in the transaction. The denormalized transactionpage, once generated and stored in the netting database 112, may furthercontain additional information that facilitates the operation of thenetting system 100. In one preferred embodiment, each denormalizedtransaction page further contains reference data to transactions,collections, settlements and the various versions of each, as discussedin other portions of this disclosure.

FIG. 4A illustrates an exemplary set of transactions that may receivedat the netting system 100. As seen, the netting system 100 may generatea corresponding denormalized transaction page in the netting database112 (represented as “denormalized transaction”) for each of thetransactions received.

The netting engine 104, in the preferred embodiment, may process atransaction for netting only when it is made available for netting. Inone preferred embodiment, a transaction received at the netting system100 is available for netting when a denormalized transaction page iscreated in the netting database 112, which may occur automatically whenthe transaction is received at the netting system 100. In anotherembodiment, a transaction is available when a flag or other indicatorswithin a transaction page, indicate that the transaction is availablefor netting. Thus, the netting engine 104 may track the nettingdatabases for new denormalized transaction pages or for such indicatorchanges. A user of the netting system 100, using a user interface, mayselect a transaction to be made available for netting from a set oftransactions that have been received. As such, not all transactionsreceived at the netting system of such embodiments are automaticallymade available for netting. Rather, only a subset of transactionsspecifically chosen by a user will be available.

When a transaction is available for netting, the netting engine 104 mayassociate the transaction page with one or more collections according toa hierarchy of netting rules. The netting rules may be executed todetermine the association of a transaction in response to the generationof a denormalized transaction page. Furthermore, the netting engine 104may be configured to associate one or more transactions with acollection at regular intervals, at predetermined times, or on command.

A transaction may not be associated with any collections right after ithas been stored at the netting database 112, as it may be not becaptured by any netting rule then in existence at the netting system100. Instead, a transaction may subsequently be associated with acollection when a netting rule is created or modified (and in some caseswhen it is deactivated). Similarly, a transaction may be subsequentlyassociated with a collection when the transaction is modified.Furthermore, a transaction may be associated with a collection throughthe selection by a user of the system through the use of a userinterface. Thus, the user may select the specific transactions fornetting, thereby automatically associating the transaction with otherselected transactions into a collection.

The netting engine 104 identifies the transactions that should beassociated with a collection by examining one or more attributes and/orconditions defined by the netting rules. Thus, when a transaction ismade available for netting, the netting engine 104 may execute eachnetting rule to determine whether the transaction may be captured by arule. Similarly, when a transaction is modified, each netting rule maybe executed to determine the association of the transaction as modified.

The netting engine 104 may execute the netting rules according to thehierarchy of the netting rules. Higher priority rules may be processedagainst the received transactions first, followed by the lower priorityrules. Thus, in the preferred embodiment, the transaction-specific rulesmay be processed first, followed by the general rules. FIG. 4B depictsan exemplary block diagram depicting the association of the transactionswith collections 412, 416 and 420 according to transaction-specificrules 400 and 404 and general rule 408. As seen, transaction-specificrules 400 and 404 have priority over the general rule 408. The nettingengine 104 may execute the general rule 408 after executing alltransaction-specific rules, including rules 400 and 404. As illustrated,a user may identify that transactions B, C, D and E should be netted.Similarly, a user may identify transaction A as a transaction to benetted with other transactions associated with collection 412. In theillustrated case, transaction Z may be associated with collection 420 inaccordance with general rule 408, a rule that captures all transactionsgreater than $250 and associates them with collection 420. Notice thateven though general rule 408 sets forth attributes that also capturetransactions A, B and D, their associations are dictated bytransaction-specific rules 400 and 404, which have priority over thegeneral netting rules, including rule 408. Furthermore, note that inFIG. 4B (and similarly in FIGS. 4C-4F), the transactions depicted mayrepresent transactions that are available (e.g., via denormalization orflagging) for the netting engine 104 to perform netting operations on,such as associating the transaction with one or more collections.

As seen, a transaction may be associated with a collection even if thereare not yet any other transactions from which the netting engine 104 mayperform netting. A user may use this feature to make sure that any netsettlement value that is calculated includes particular transaction A.

In certain embodiments, the hierarchy of netting rules may not bestrictly followed by the netting engine 104. For example, when atransaction-specific rule is defined by a user of the netting system,the netting engine 104 may execute only the rule created. Thus, when auser selects a number of transactions for netting through a userinterface or identifies through a transaction identifier the transactionfor netting, the netting engine 104 may automatically associate theselected transactions with a collection as defined by thetransaction-specific rule. The netting engine 104 may not execute othertransaction-specific rules or general rules.

In some circumstances, only general rules may be executed. In onepreferred embodiment, for example, the netting engine 104 may executeonly the general rules when the netting system 100 receives a newtransaction at the netting system 100. Because the transaction-specificrules only identify specific transactions that should be netted,processing efficiency may be achieved by avoiding the execution oftransaction-specific rules altogether when a new transaction is justreceived at the netting system 100. Thus, this embodiment operates underthe assumption that when a transaction has just been completed, it isunlikely that, when received at the netting system 100, the user hasalready chosen the transaction for netting, i.e., it is unlikely that atransaction-specific rule would identify the new transaction. Indeed, incertain embodiments, no such transaction-specific rules may yet existwhen the transaction is received at the netting system 100, as the usercannot select the transaction and create a transaction-specific ruleuntil it is associated with a collection via a general rule.

The transaction-specific rules may further associate the transactionpage with one of several collections based on any number of attributesthat describe a transaction, including a transaction's marketinformation, currency of the trade, commodity traded, quantity of trade,schedule of trade and other information well known by a person ofordinary skill in the art. Thus, as seen in FIG. 4C, specific rule 404may set forth that transactions that are selected, in this casetransactions B, C, D and E, should be associated with differentcollections based on the currency used in each transaction. As a result,denormalized transactions B and D, which are dollar-based transactions,are associated with collection 416, while denormalized transactions Cand E, which are euro-based transactions, are associated with collection418.

The association of the transactions at the netting system 100 is alsodetermined when a rule is created at the netting system 100. Thus, thenetting engine 104 may reprocess all denormalized transaction pages inresponse to the creation, modification or removal of a netting rule. Inone preferred embodiment, the processing of all transactions may belimited to only those transactions that are not associated with atransaction-specific rule and only when a general rule is created. Inthis embodiment, in response to the creation of a specific rule (e.g.,through the specific selections of transactions by the user fornetting), the netting engine 104 may process only the selectedtransactions. Further, in response to the modification, removal, ordeactivation of a netting rule, the netting engine 104 may only examinethe transactions previously captured by the netting rule.

Once transactions have been associated with at least one collection atthe netting system 100, the netting engine 104 may determine a nettransaction value for the collection according to netting accountingpractices that are utilized and well known in the art by a person ofordinary skill. The netting engine 104, in particular, takes intoconsideration the settlement value for each of the transactionsassociated with a particular collection in determining the netsettlement value. For example, the settlement values of each transactionmay be aggregated to determine a net settlement value. Taking thetransactions associated with collection 416 of FIG. 4B as an example, anet transaction value may be determined to be $800 owed to party 2because in the aggregate, party 2 is owed a total of $1200 and, at thesame time, owes $400. Rather than four separate transfers, one singlepayment may be made to settle transactions B, C, D and E.

In several embodiments of the present invention, the settlement positionmay be determined for a subset of transactions in a collection. A user,for example, may select the transactions that he or she would like todetermine a net value from a collection of associated transactions thatare provided in accordance with a transaction-specific rule.

The netting engine 104 may determine the net settlement valueautomatically in response to a generation of one or more collectionpages in the netting database 112. A net settlement value may bedetermined automatically when one or more transactions are associatedwith a collection, when the set of transactions associated with acollection is modified, or when the attributes of any associatedtransaction (e.g., settlement value) are modified.

Once the netting engine 104 has determined the settlement values of aset of transactions, the netting engine 104 may provide the user of thesystem with the information via a user interface. Through the use of auser interface, such as at the client device 114 of FIG. 1B, the usermay view the transactions from which netting may be completed. Forexample, the user interface may display the transaction partner, thetransactions, the net settlement value and the currency of eachcollection of transactions. The user may select each collection (orsub-collection thereof) and approve or deny a transaction for netting.Through this determined information, the user of the system maycommunicate the transactions and settlement information with arepresentative of the trading partner through traditional methods suchas the telephone or email. This negotiation and approval process mayalter the transactions that are to be settled and the settlement values.Once the trading partner has approved the settlement, the user of thesystem may cause the transactions to be settled for the determinedsettlement value such as by indicating to the netting engine 104 thatthe collection of transactions are to be settled for the determinedsettlement value through the use of the user interface.

In another embodiment, the approval and negotiation process may be builtinto the system. At the direction of the user, the netting engine 104may transmit a settlement request to the trading partner system, whichmay receive the request as an email or as other forms. Thus, asettlement request email generated and transmitted by the netting system100 may include all of the information necessary to indicate to arepresentative of the trading partner the transactions for settlement,the settlement value, and other information. The settlement may also bescheduled according to a predetermined payment schedule. Similarly, thenetting engine 104 may cause the settlement information to betransmitted to the financial market 130.

The email may, for example, contain a hyperlink or other similarfunctions, that when pressed, automatically causes the netting system100 to receive notice of the approval of the settlement through the userinterface. In another embodiment, the email may contain a link to awebsite that allows a representative of a trading partner to log in(e.g., authenticate) and view the settlement requests from the nettingengine. The representative may utilize the website to approve, deny ormodify the transactions that will be netted and the net settlement valueor to propose transactions for settlement. The interface may allow thetrading partner representative to select other transactions at thenetting system 100 to be included (or similarly those that should beexcluded) for netting.

In one embodiment, the netting engine 104 and trading partner systemsmay utilize a common application programming interface (API) that allowsthe system of the trading partner (e.g., trading partner system 126 ofFIG. 1B) to receive and process the request transmitted from the nettingengine 100. The trading partner system 126 may automatically display thesettlement requests on a user interface including the settlement-relatedinformation. Just as with the request website, a user at the tradingpartner system 126 may approve, deny or modify the settlement request orpropose transactions for settlement, all through the use of a userinterface. The netting system 100, similarly, may automatically receivenotice of the response and provide the user of the netting engine 100with the response automatically. In at least one embodiment, if theresponse is an approval of the request, the settlement is automaticallycompleted according to the settlement request.

Thus, in certain embodiments, including those in which a trading partnermay propose, approve, deny or modify net settlement requests through theuse of a web-accessible web site or through the use of an API, thenetting system 100 may further be configured to provide to the user alist of trading-partner settlement requests and responses to requests.

Other forms of communications may be used other than email andnetwork-based communications. For example, a voice message may begenerated indicating all of the necessary information of the settlementproposal. Similarly, a text message may be generated and transmitted. Auser of the trading partner who has received the message may reply toapprove, deny, modify or propose new transactions. Thus, a user mayinteract via voice commands or through dial tones in response to a voicecall or through preset commands via text messages. Furthermore, thenetting system 100 may be configured to leave a voice message describingthe proposed settlements or leaving a number to call back.Authentication may be necessary if these forms of requests are used.Other forms of communication are well within the scope of the inventionincluding faxes, radio-based communications, application-basedtransmissions (e.g., mobile applications), traditional paper-basedcommunications and others.

In at least one embodiment, netting engines of various financialinstitutions may automatically communicate with one another to negotiatea net settlement based on each institution's transactions, collections,settlements, netting rules, system conditions, preferences and otherfactors. The netting systems may automatically generate net settlementvalues and complete the settlement of the transactions involved withoutuser intervention. The net settlement of transactions may also benegotiated and agreed upon by three or more netting systems.

It should be readily apparent that the present invention allows for thenetting engine 100 to communicate its settlement requests, negotiate andreceive responses from even preexisting computer systems of a tradingpartner through the use of an API or other methods disclosed herein.

Once a collection of transactions has been approved for settlement basedupon an agreed upon settlement value, the netting engine 104 may furtherfacilitate the settlement of the transactions. The netting engine 104may communicate with one or more engines or components of the systemthat are responsible for the settlement of transactions with tradingpartners. The netting engine 104, for instance, may communicate to asettlement engine the specific transactions that are to be settled, thetrading partners involved, the currency information, the settlementvalue, as well as other information that may be necessary in order fortransactions to be settled according to well known accounting practices.In one embodiment, the netting engine 104 may have such settlementcapabilities incorporated into the netting engine itself. The nettingengine 104 may contact a bank 132 (FIG. 1B) and request a wire transferof the net settlement value to a trading partner 134 (FIG. 1B) or atrading partner system 126 (FIG. 1B) via network 116 (FIG. 1B). Otherforms of settlements may be used, in accordance with common settlementpractices.

In at least one embodiment, the netting engine 104 may cause anotification to be provided to the trading partner 134, describing thesettlement, including the netting calculations and the transactions thatare involved, to indicate that the settlement of the transactions havebeen completed.

At the same time or soon thereafter, the transaction pages in thenetting database 112 may be updated to indicate that the individualtransaction has been settled. Thus, as seen in FIG. 4D, a settlement 422is completed and recorded for the transactions associated with thecollection 416. In certain embodiments, each previous version of thetransaction page may be marked as settled to prevent future settlementsfor the same transaction value. Furthermore, the net settlement may bestored in a settlement page within the netting database 112.

FIG. 3A depicts a flow chart of an exemplary netting method inaccordance with a preferred embodiment of the invention. These steps,for example, may be performed at the netting engine 104. At step 300, anew transaction is received. At step 304, a denormalized transactionpage may automatically be generated in response to each transactionreceived. The netting system 100 may then associate the denormalizedtransaction page with a collection according to one of a plurality ofnetting rules and in accordance with a rules hierarchy at step 308.Furthermore, at step 312, the net transaction value for each of thecollection containing two or more transactions may be determinedaccording to netting accounting practices well known and utilized in theart by a person of ordinary skill. At step 316, the netting engine 104may facilitate the settlement of the transactions based on thedetermined net settlement value.

As a person of ordinary skill in the art would recognize, fromtime-to-time, modifications may be made to a transaction, even after asettlement has been made. Such modifications may include, but are notlimited to, a change to the settlement value, to the parties involved,or the schedule of payments. In fact, a modification may be made to anyinformation related to the transaction. In certain circumstances, atransaction may be canceled altogether. The netting engine 104 has thecapability to react to such modifications and take into considerationsuch changes in calculating subsequent net settlement values.

For example, FIG. 3B depicts a flow chart of an exemplary netting methodin response to a modification to a transaction, in accordance with apreferred embodiment of the invention. At step 320, an update ormodification may be received at the netting engine 100. The nettingengine, in response, generates a denormalized transaction page at step324, corresponding to the transaction that has been updated. At step328, the association of the transaction may be updated according to themodified transaction. Furthermore, at step 332, the net transactionvalue for an updated collection containing the updated transaction maybe determined. Finally, the transactions contained in the updatedcollection may be settled by the netting engine 104 at step 336.

Specifically, when a modification to a transaction is received at thenetting system 100, the netting engine 104 may generates a newtransaction page, which may be, in one embodiment, a denormalizedtransaction page containing the transaction information as modified. Thepresent invention may generate additional denormalized transaction pagesfor each version of a transaction, each of which may contain informationreferencing the previous version of the denormalized transaction. Thisensures that the netting system 100 maintains data integrity and acomplete audit trail as discussed in detail in other portions of thisdisclosure. When flags or indicators are used within the transactionpage to indicate transactions that are available for netting, the flagsor indicators may be automatically activated when transaction pages aregenerated for existing transactions that have been modified or removed(i.e., new versions).

When a transaction is removed, the netting engine 104 may, nonetheless,generate a transaction page in the netting database 112. The transactionpage may contain a null transaction value or data indicating that thetransaction has been removed. The denormalized transaction page that isgenerated, referred to as a tombstone, may also reference previousversions of the transaction. An example of the transaction page after ithas been removed is depicted in FIG. 4F.

In response to the generation of a denormalized transaction page or theactivation of the netting flag/indicator, the netting engine may updatethe association of the transaction with a collection by executing one ormore rules in similar fashion as the initial association of thetransaction.

Based on the association of a transaction prior to its modifications,the netting rules that are executed in response may differ. For example,if the transaction was associated with a collection in accordance with ageneral rule, the netting engine 104 may reexecute all general rulesonce again to determine the proper association. The modification of thetransaction, for example, may have altered an attribute of thetransaction that causes the transaction to no longer be captured by thesame general rule or causes the transaction to be captured by anothernetting rule. In contrast, if the transaction was associated with acollection in accordance with a transaction-specific rule, the nettingengine 104 may automatically execute the same transaction-specific ruleto determine whether the transaction-specific rule still captures themodified transaction. If not, the transaction may be disassociated fromthe transaction-specific rule and corresponding collection. The generalrules may then be executed against the modified transaction.

In response to a modified transaction and a differing collectionassociation, the netting engine 104 may create a new collection page inthe netting database 112 and associate the generated denormalizedtransaction page with this new version of the collection. The collectionpage may reference the previous versions (i.e., collection pages ofprevious versions). As seen in FIG. 4E, where the transaction E has beenmodified to transaction E′, containing an increased settlement value of$500, the netting engine 104 may associate transaction E′ with acollection 416′, along with transactions B, C and D, as previously. As aperson of ordinary skill in the art would recognize, the previousversion of transaction E—represented as denormalized transaction E—isaccordingly not associated with collection 416′. However, it should benoted that the collection page of collection 416 in the netting database112 may still reference the same denormalized transactions B, C, D andE, even though transaction E has been modified and transactions B, C,and D are also associated with collection 416′. In other words, previousversions of collections, transactions rules, and settlements are notmodified where the underlying transactions have changed apart from theaddition of reference data. Indeed, collection 416′ may containinformation referencing collection 416 and vice versa. Even where atransaction is removed, a collection 416′ may nonetheless reference thetombstone denormalized generated page, as seen in FIG. 4F.

In response to the association of the new transaction page with acollection, the net transaction value may be determined according tonetting accounting practices that are utilized and well known in the artby a person of ordinary skill, similar to the calculations of the nettransaction value of the collection prior to a transaction modification.The settlement value for each of the transactions associated with aparticular collection 416′ may be taken into consideration to determinethe net transaction value. Furthermore, the netting engine 104 takesinto consideration previous settlements. In fact, where a settlement hasbeen completed previously, differences between the previousnet-settlement value and the settlement value of collection isdetermined The result is the net-settlement value reflecting themodifications made to the transaction. For example, the net-settlementvalue of the transactions associated with collection 416 was $800, whichwas settled previously with party 2. In response to the modification ofthe transaction value of transaction E (increasing the settlement valueto $500), the net settlement value based on the associated transactionsis $900. However, because an $800 settlement was previously completed,the net settlement value of collection 416′ is determined to be $100.Thus, when a settlement was previously entered, only this difference inthe settlement value needs to be paid to entity 2. Once a net settlementvalue is determined, the settlement may be entered and completed insimilar fashion as with the initial settlement.

The netting engine 104 further has the capability to processmodifications or removal of netting rules. When a general rule ismodified, the netting engine 104 may reexecute each general rule anddetermine the association of each transaction in the netting system 100.In one embodiment, the netting system 100 may only reexecute themodified rule against each of the transactions previously captured bythe rule.

When a transaction-specific rule is modified, the makeup of thecollections may change entirely; transactions that may be captured by aparticular transaction-specific rule may no longer be captured by anytransaction-specific rule, may be captured by a general rule, or may notbe captured by any rule at all. As a result, the netting engine 104 mayexecute all transaction-specific rules and the general rules against alltransactions at the netting system 100. Using FIG. 4B as an example, inresponse to a change in specific rule 404, the netting engine 104 mayexamine each of the transactions A through Z against specific rules 404,408 as well as general rule 412. The resulting collections may differdramatically.

As a person of ordinary skill in the art may recognize, when amodification is made to either types of rules, the netting system 100may be required to reprocess the rules for each of the transactions atthe netting system 100. In fact, the amount of resources and processingefforts utilized by the netting engine 104 may be especially substantialwhen a transaction-specific rule is modified. Indeed, the differences inthe processing power that is required to effectuate a modification to aspecific rule versus a general rule may be dramatic because in actualpractice the netting system 100 may contain tens of thousands oftransaction-specific rules while only containing tens or a few hundredgeneral rules that need to be reexecuted.

In one preferred embodiment, the reexecuting of specific rules may beavoided altogether in response to the modification, deactivation orremoval of a transaction-specific rule. By including information withineach transaction page at the netting database 112, indicating thetransaction-specific rule that captures a particular transaction, all ofthe specific rules need not be reexecuted each time atransaction-specific rule is modified. Rather, this information, whichmay be included within each transaction page as “specificRule” variable,may reference the rule that captures the transaction. Thus, in theexemplary method shown in FIGS. 3A-B, when a transaction is associatedwith a collection (steps 308, 328), the specificRule variable containedwithin the transaction page may be modified to reference thetransaction-specific rule.

Similarly, when a transaction-specific rule is created that causes atransaction previously captured by a general rule to be captured by atransaction-specific rule, the specificRule value may simply be modifiedto reference the specific rule. The netting engine 104 may automaticallyexecute the transaction-specific rule referenced in response to anychanges in value of specificRule. Under this implementation, no otherspecific rules need to be processed.

If a transaction-specific rule is modified, the netting engine 104 maydetermine all transactions that are captured by the modified rule byexamining the specificRule variable value. In response, each of thesetransactions may be reexamined against the modified transaction-specificrule. Where a transaction is no longer captured by thetransaction-specific rule as modified, the netting engine 104 may modifythe specificRule value of a transaction page to a null value. The changein the value of specificRule may cause the netting engine 104 toautomatically execute all general rules to determine the transaction,and the association of the transaction. As seen, this featureimportantly avoids the reexamination of all of the transaction-specificrules and saves much processing resources. In one embodiment, thespecificRule value further indicates the general rule with which it maybe associated with.

Furthermore, if a transaction-specific rule is deleted or simplydeactivated, the value of specificRule may simply be modified once againto a null value. This may automatically cause the netting engine 104 toautomatically reexecute the general rules to determine transactionassociation.

While the use of the specificValue may still require the netting engine104 to reexecute all general rules, the resources and processing thatthis may require is minimal relative to those required in reexecutingeach transaction-specific rules, which may number in the thousands.

In one embodiment, the specificRule value further indicates the generalrule with which it may be associated with. In another embodiment, thenetting engine 104 records and tracks the netting rules that eachtransaction may be captured by. For each transaction previously capturedby a modified netting rule, the netting engine 104 may be configured toautomatically determine the most recent netting rules that have capturedthe transaction and predict therefrom a netting rule that may apply. Bythis method, further efficiency may be achieved by minimizing thenetting rules that are examined in response to the modification,deactivation and removal of a netting rule.

The above-described exemplary method provides a general description ofone of several aspects of the invention which dynamically determines,groups and processes any number of transactions according to knownnetting accounting practices through the use of a hierarchy of nettingrules. These examples and embodiments are merely illustrative of thenetting system of the present invention.
